POWDER-PLACING SYRIN Application filed July 16,

My invention relates more particularly to an improved and simplifiedsyringe for discharging powder and the like into cavities, and it has atits main object'to provide a syringe bulb and tube adaptedto have in- Isorted therein, or connectcdtherewith a capsule or the like containing apredetermined amount of the powder or matter to be discharged into thecavity, whereby it is possible to prepare the powder in the form ofloaded capsules which can be quickly and readily put into place in thesyringe and inserted into the cavity for discharge by the comprescapshave been removed, and indicating in light broken lines the removal ofsaid end caps and the placement of the capsule body upon the end of saidtube;

Figure 3 is aside elevation of the removamable sleeve or nozzle which isplaced over the capsule body after the latter has been placed on the endof the tube; and

Figure 4; is a view showing a slightly modified form of the invention,and in which a spring collar is used to lock the capsule in place on theend of the tube, instead of using the sleeve shown in Fig. 3.

Referring now more in detail to the drawings, my invention as hereillustrated, comprises a syringe tube or body 5, with a bulb 6, forfurnishin a blast of air, the end of the tube or body 5, being providedwith a collar or abutment flange 5, and a small stud 7, the outermostend of said tube being further reduced, as at 5, to receive the end of acapsule body, designated 8, and indicated in light broken lines in Fig.2, and in section in Fig. 1. Said capsule body may be of any suitablematerial and provided with caps, 9, 9, or other closure means which canbe removed in order to place the capsule over the end 5 of the syringetube 5, as indicated. Said capsules can be provided in quantity andloaded with the desired powder or other medicinal matter to be used with,a syringe and used as needed. A sleeve or nozzle member 10, is providedto 1927'. Serial No. 206,3245

telescope over the capsule body after it. has

been placed upon the end of the tube 5, said sleeve or nozzle having abayonet slot, 11, by

means of which it'interlocks' with the stud 7,

as shown, for the purpose of securing the capsule 1n place. The outerend of said sleeve or nozzle 10, is provided with a slightly reducedoutlet or discharge opening, 10, forming an abutment shoulder 10, forthe outer end of the capsule, as clearly illustrated in the sectlonalview, Fig. 1.

A capsule body ma? be provided which can be used without the s eeve ornozzle, as designated at 12, Fig. 4, and I have provided a sprlngcollar, 13, having a, bayonet slot, 14,- to interlock with the stud 7,said spring collar having the spring fingers 13, adapted to yieldinglyhold the capsule as said collar is put into place over. the body of thecapsule and interlocked with the end of the syringe tube, as clearlyillustrated in Fig. 4.

Thus I have provided a very simple, practlcal and economical syringedevice for use with preloaded capsules for discharging a given amount ofpowder or other medicinal matter in dr form into a cavity which can onlybe reac ed by the insertion of a tube or nozzle of some kind, and whileI have lllustrated my invention for descriptive purposes, I do not limitit to the details of construction and arrangement shown, except as Imaybe limited by the hereto appended claims.

I claim I u i I I 1 In 'comblnatlon, asyringe body or tube adapted toreceive a capsule, a capsule adapted to fit telescopically the endofsaid tube, and detachable means for securing said capsule in place onsaid tube with both ends open,

and means forming apart of said syringe for forcing a blast of airthrough said tube and said capsule for discharging the contents of saidcapsule.

2. In combination, a syringe having a tubu- 1 0 lar part adapted toreceive in telescoping relationship therewith a capsule, a capsulepreloaded with matter and adapted to have its ends opened and connectedwith said tubular part, and means fitt ng over said capsule and 3. Incombination, a'syri'nge tube for insertion into a cavity, a capsuleadapted to be telescopically connected with the end of said tube, saidcapsule being adapted to contain matter to be discharged therefrom by ablast from said syringe tube. means forming :1 part of said syringe forcreating a blast of air through said. tube and said capsule, and a.member udupted to telescope over said capsule and to interlock with saidtube for bolding so id capsule in place.

4. In combination :1 svringe having: a part adapted to receive and hold:1 capsule like element containing matter a preloaded capsule adapted tobe connected therewith in such relationship that. be. operation of thesyringe discharges the contents from said capsule, and means telescopingthereover for holding the capsule like element in place. on said syringepart whereby said capsule can be inserted into a cavity for dischargingits contents therein by the operation of said syringe.

5. A syringe of the character referred to including in combination a.bulb. a tube having a reduced portion to receive thereover a capsulebody, a capsule body adapted to be telescoped with said reduced portiona member adapted to be placed over said capsule body and over saidrcduced'portion and interlocked with said tube for holding said capsulebody in place, whereby the operation of said syringe bulb forces thecontents of sziid eupsule body therefrom, for the purpose described.
